Perfect Dark

Disarm a guard and he will usually pull out a Falcon 2. Shoot the guards in the leg after they have been disarmed, and they will either surrender or will run off, leaving a small blood trail behind. Knock the guards out and they will still move on the floor when you punch them. When they have been shot, then they will just lay still.

Enable any or all the cheat codes. Get to the area where you destroy the box to get the Bombspy. Destroy the box with any explosive and walk over the white suitcase that appears. Then, open the door by the limousine to go down the ramp to get into the Pond Punk. Kill the guards by any method. Use the Farsight to see through the locked door that lets you enter the Pond Punk. Fire a shot besides the man standing inside. He will open the door to try and kill you -- kill him. Then, go to your left and enter the restroom. Walk to the last stall all the way at the end of the restroom. Equip the Bombspy. Fly it into that stall, then press Start to unequip the Bombspy. Walk all the way back and leave the Pond Punk by yourself. Once the doors close you will see that you cannot get back inside by pressing B. Press Start again, equip the Bombspy, and fly it to the door. Press B to open it. Then, fly the Bombspy back to where it was and unequip it. You can now walk yourself back inside the Pond Punk.

Enter the Pond Punk Club, which is the room next to the limo. When you enter, be careful of the man that is down the ramp -- pick him off quietly to prevent alarming the other guards in the room below. Now, stand outside the door and equip your Falcon 2 scope. Open the door and fire your guns to alarm the guards in the locked room. When the door opens, you will notice that you are in a strip club. Run to your left to the bar and get your Falcon 2.

Go by the limo and you will see a pair of doors. Go through them and down the ramps. Disarm the guard and he will open up the locked doors leading to a room with a pole on a table and a bar.

This is a simple move, but priceless to master. Hold Analog-stick Left then hold C-Right. You will circle an invisible point in the center. Practice doing this around a crate, trying to keep your gun cursor/sights on top of it. Also, try doing this with holding Analog-stick Right and C-Left to circle in the other direction. This makes will make you harder to hit, but will keep the enemy in your sights at the same time. If your sight starts to drift from your target, just adjust your angle on the Analog-stick.

There is a slightly hidden area in the multi-player level "Complex" that is very easy to reach. Just look for a small area in the wall that has metal grates on three sides. You can climb up one of the sides. Then, run on the roof over to an item in the opposite corner (Item #5).

Think of the main room in Complex that has two big ramps and a sniper window looking in. If you ever feel cornered, just run under a ramp, as though you were trying to climb up the ramp from the back. It looks like you are going to have to duck down to fit, but at the last second you will magically pop up on top of the ramp, which will disorient your opponent enough to let you turn around and run off up the ramp.

Use the following trick when you have an opponent in multi-player mode who is using Slayer missiles to hunt you down, making it impossible for you to get close to him or her. Get an explosive weapon (preferably the SuperDragon in grenade mode). Just as you see the missile flying towards you, trigger the explosive. Make sure it is not too close or you will get caught in the blast. If aimed correctly, the flames should catch the missile and it will explode.

Have one human player take control of Joanna and another human player take control of a guard. Have the player as the guard kill the other guards for Joanna to easily pass the level The other guards will not shoot back - they will just run away if they are not killed.
